Which term describes a person who can see distant objects clearly but cannot bring near objects into focus?

Explanation:
When the eye has trouble bringing close objects into focus but distant objects look clear, it’s because the eye isn’t converging light from near objects enough to land it on the retina. This condition is farsightedness, or hyperopia. The lens and eyeball are not powerful enough to focus near images, so near objects appear blurry, while far objects can be seen more easily because their light can be focused with less eye-strain. So the term that fits is far-sighted. Near-sighted would mean clear near objects and blurry distance, astigmatism causes blurry vision from an irregular cornea, and a plane mirror isn’t a vision condition.
